Japan’s actions regarding the disposal of radioactive water from the Fukushima nuclear disaster are not only concerning but also set a dangerous precedent for other governments, particularly in Asia. With over 140 nuclear power reactors already in operation in the region and dozens more under construction or in the planning stages, the implications of Japan’s actions are far-reaching.
The situation in Fukushima is complex. The damaged reactors contain melted nuclear fuel debris, which is being cooled by pumped-in water. This water comes into contact with radioactive substances known as radionuclides, creating a toxic cocktail. Additionally, approximately 100 tons of groundwater and rainwater leak into the reactor buildings each day, becoming contaminated. To manage this, a filtration system is used to remove much of the radioactivity, and the water is stored on-site in large steel tanks. However, the volume of water continues to increase, and space for storage is running out.
The International Atomic Energy Agency (IAEA) and the Japanese government have explored various options for dealing with the water. The IAEA has advised considering discharging it into the sea, while other options such as releasing it as vapor or injecting it deep underground have been considered. However, experts and environmental groups have criticized the lack of public input and the failure to seriously evaluate potential alternatives like long-term storage in more robust tanks.
Despite opposition from citizens, the fisheries association, and neighboring countries like South Korea and China, the government made the decision to release the water into the ocean in April 2021. Public hearings were conducted, but they appeared to be more focused on promoting the ocean release option rather than genuinely involving the public in decision-making. It was only months later that a radiological environmental impact assessment conducted by Tepco, the company responsible for the Fukushima plant, was released, raising concerns about information gaps and the absence of a comprehensive inventory of radioactive elements in the tanks.
In contrast, successful examples of involving stakeholders in decision-making can be found elsewhere. In Belgium, regulators empowered a broad cross-section of the public and private stakeholders to choose a site for a long-term repository for low-level radioactive waste. This approach led to competition between neighboring towns, and ultimately, a proposal by the municipality of Dessel was approved. Similar processes have been implemented in Finland and Sweden for nuclear waste facility siting.
It is crucial for Japan and other governments to recognize the importance of transparency, public input, and thorough evaluation of alternatives in managing nuclear disasters. Failure to do so not only raises safety concerns but also erodes trust and sets a dangerous precedent for future actions.
